Purpose

The various forms of vascular diseases are complex in their origins and their manifestations.
Their successful treatment (either endovascular or surgical) strongly depends on the exact knowledge of the vascular structure of the patient. We have developed a software system called MedVis 3D ,
that offers interactive 3D visualization of cerebral vessel structures to support aneurysm diagnosis,
risk-assessment and treatment.
The following key features help to improve and alleviate aneurysm...

Methods and Materials

3D Reconstruction In the course of the research project MEDVIS 3D ( www.medvis3d.at ),
a clinical software application has been developed,
capable of 3D reconstruction and visualization of intracranial aneurysms based on 2D medical image data from CTA,
MRA,
or DSA. Our software reconstructs the 3D blood volume from 2D images,
which can be visualized by direct volume rendering,
using the OpenGL graphics library. Aneurysm Segmentation A thinning algorithm can be applied to the volume to perform...

Conclusion

Clinical relevance Our medical partners (Landesnervenklinik Wagner Jauregg - Linz and Allgemeines Krankenhaus der Stadt Linz) are integrated in the development process and are evaluating the system in their clinical environments.
First results are very promising and show high clinical relevance for identifying high risk areas in cerebral aneurysms. Comparison of our simulation results with commercial systems (FLUENT,
ABAQUS) shows a high level of agreement. Outlook Together with our medical...
